ELECTRIC BRUSH.

SPECIFICATION forming part of Letters Patent No. 771,274, dated October4, 1904. Application filed February 27,1904:- Serial No. 195,523. (Nomodel.)

To all ZUhOTH/ it may concern.-

Be it known that we, ALBERT T. SANDEN and VICTOR SENOE, citizens of theUnited States, and residents of the borough of Manhattan, city, county,and State of New York, have invented certain new and useful Improvementsin Electric Brushes, of which the following is a specification,accompanied by drawings.

This invention relates to electric hairbrushes; and the objects of theinvention are to improve upon the construction and efiiciency of suchbrushes and secure a ready means of applying a current of electricity tothe scalp when brushing the hair, thereby obtaining all the usefulresults from the application of electricity to the skin.

Further objects of the invention will hereinafter appear; and to theseends the invention consists of an electric hair-brush for carrying outthe above objects embodying the features of construction, combinationsof elements, and arrangement of parts, having the general mode ofoperation substantially as hereinafter fully described and claimed inthis specification and shown in the accompanying drawings, in whichFigure 1 is a longitudinal sectional view of a brush embodying theinvention. Fig. 2 is a transverse sectional view of Fig. l on the linea: m. Fig. 3 is an enlarged detail View of an element of the pile and aninsulator for the pile. Fig. 4: is a top plan view of the pile and aportion of the brush.

Referring to the drawings, A represents a suitable body for a hair-brushof any desired material having insulating properties. The bristles B arepreferably of some suitable metal and are all connected to or inelectric connection with a metallic plate (J, over which in thisinstance is placed the insulating-plate D, preferably of rubber. Theplates G and D, together with the bristles, are suitably held upon theface of the back by means of the metallic rim E held against the body Aof the brush in any suitable manner, as by means of suitable pins.

The metallic or conducting bristles B are adapted to be placed incircuit with an electric accumulator or pile F. In order to accomplishthis end, a metallic strip or contact G is suitably secured in thisinstance to the top of the handle of the brush by suitable pins H. Ametallic pin I, forming a contact, extends from the plate C through theback of the brush and affords provision for including the pile incircuit with the bristles. Another pin, J, extending from the plate orcontact G, affords additional means for securing the pile in position.It will be seen that when the pile F is secured between the pins J and Ian electric circuit may be completed through the hand and the head whenthe hair is brushed, because one pole of the pile connects with thebristles and the other pole connects with the plate or strip G, so thatwhen the handle is grasped in the hand and the brush applied to the heada complete circuit will be made through the body. In this instance theelectric pile F consists of plates of different metals placed in pairs,said pairs being insulated from each other. When the pile is dipped inweak acid or vinegar and placed in position on the brush, a differenceof potential will exist between the poles of the pile, whereby anelectric current may be passed through the hand and head or throughother parts of the body if the brush is used for purposes other thanbrushing the hair.

Preferably the plates K are of copper and the plates L are of Zinc,placed side by side and in contact with each other, while between eachpair of plates is arranged a suitable insulator-as, for instance, apiece of blottingpaper 0. Preferably the plates and the blotting-paperare provided with projecting portions P, which substantially registerand serve to maintain the plates firmly in position, so that they cannotget out of alinement. At one end of the pile there is a metallic plateQ, provided with means for attaching the plate to the projecting pin I.In this instance a loop R is formed on the outside of the plate Q,adapted to slip over the pin I and place one pole of the pile in circuitwith the bristles. If the plate Q is of zinc, the plate S at the otherend of the pile should be of copper and likewise provided with a loop Tto slip over the pin J.

Suitable means are provided for maintaining the elements of the piletogether, in this instance bands U being passed around the pilelongitudinally. The bands U should be maintained out of contact with theelements of the pile, and preferably an insulator V, of rubber or othersuitable material, is arranged at one end of the pile, and saidinsulator V and the plate Q are wider than the elements, so that thebands U are maintained out of contact with the elements and electricallyinsulated therefrom by reason of the insulator V.

If desired, a cover W may be hinged to the brush and provided with acatch X. The cover W prevents dust and dirt from reaching the pile. Itwill be seen that the pile F as a whole may be removed from the brushand applied thereto as desired, and different piles of differentstrengths may thus be applied to the same brush, as desired.

According to this invention a neat, simple, and efficient electrichair-brush is secured which is cheap to manufacture and is not liable toget out of order. A useful and stimulating effect is obtained upon thescalp, which is not so great as to injure the parts to which the currentis applied.

Obviously some features of the invention may be used without others, andthe invention may be embodied in Widely varying forms.

Therefore, without limiting the invention to'the constructions shown anddescribed nor enumerating equivalents, we claim, and desire to secure byLetters Patent, the following:

1. The combination with a hair-brush, of an electric pile connectedthereto, said pile comprising metallic plates insulated in pairs,

the pairs and insulating layers of suitable material having portionspressed outwardly therefrom and registering one with the other tomaintain the plates firmly in position in the pile, for substantiallythe purposes set forth.

2. The combination witlra hair-brush, of an electric pile connectedthereto, said pile having an end insulator, and bands passing around thepile lengthwise to hold the elements together, said bands beingmaintained out of contact with the elements, for substantially thepurposes set forth.

3. An electric hair-brush, comprising the frame and a metallic contactextending along the handle, bristles connected to a metallic plate, pinsprojecting outwardly from the back of the brush, one in electricalconnection with the contact extending along the handle, and the other inelectrical contact with the said plate to which the bristles areconnected, an electric pile adapted to be removably connected to saidprojecting pins, whereby said pile may be placed in circuit between thecontact on the handle and the bristles, said pile comprising a pluralityof compound elements suitably insulated from each other, and means forbinding all of said elements together.

In testimony whereof We have signed this specification in the presenceof two subscribing witnesses.
